I'm sorry, I know this has nothing to do with spoilers, but I just wanted to remind everyone what Ken Corday said back in 2010:

"EJ is also humanized by the arrival of Nicole's younger sister, Taylor. I had to use the cliché, but it's some enchanted evening. It's the moment that happens a few times or one time in your life where you meet someone and it's, 'Oh, my God.' And that's what we're banking on here with these two. "
